Teresa Shook never considered herself much of an activist, or someone particularly versed in feminist theory. But when the results of the presidential election became clear, the retired attorney in Hawaii turned to Facebook and asked: What if women marched on Washington around Inauguration Day en masse?

She asked her online friends how to create an event page, and then started one for the march she was hoping would happen.

By the time she went to bed, 40 women responded that they were in.

When she woke up, that number had exploded to 10,000.

Now, more than 100,000 people have registered their plans to attend the Women’s March on Washington in what is expected to be the largest demonstration linked to Donald Trump’s inauguration and a focal point for activists on the left who have been energized in opposing his agenda.
